I'm using momentjs (2.19.2) in my nodejs/typescript program. I import the lib using (tried both):
var moment = require('moment'); or import * as moment from 'moment';
When I write: moment().format("DD-MM-YYYY"), it returns 18-04-2018 which is correct.
Whereas: moment.duration(10000).asMinutes() returns NaN (same for other "as" methods)
It used to work correctly but now I can't figure out why these duration methods fail.

What do I do wrong with this duration or project configuration?
Thank you!

pass a unit to duration
moment.duration(10000, "s").asMinutes()
答案 1 :(得分：0)
我在使用moment.duration().asMinutes()功能时看不到任何问题。请查看以下代码段：
console.log(moment.duration(10000).asMinutes()); //working as expected
console.log(moment.duration(10000).minutes()); //working as expected<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.1/moment.min.js"></script>
注意：似乎问题出在其他地方。再次检查您的代码或共享JavaScript代码。
答案 2 :(得分：0)
好的，我终于设法摆脱了这个错误。
我删除了package-lock.json和node_modules文件夹，运行了npm i。 （这3个动作同时进行，所以我不知道哪一个是有用的）
现在，moment.duration返回一个值。
再次感谢你。
